Our Vision:
At SmartCitiesWorld, we truly believe that the Cities Climate Action Summit is helping to showcase the way cities can act against the realities of climate change and develop sustainable and resilient models across city departments.
Our events are focussed on the outcomes that cities have achieved alongside the challenges and need for collaboration to overcome climate related barriers within our cities.
Our vision is to facilitate positive change. So, although we already have the support of international bodies and partners, we strive to involve every CSO, every CTO and all those involved in the decision-making process within cities to be a part of this journey.
Together we will help create change, department by department, town by town, city by city and country by country.
Just some of the quotes that City Halls gave us:
"Cities shouldn’t wait for a new optimal technology to emerge in the future to get started because there are already so many ways to get started off the shelf."
Björn Hugosson, Chief Climate Officer, City of Stockholm
"The importance is working with other levels of government, communities and the private
sector as we just can’t do it alone."
Lord Mayor Sally Capp, City of Melbourne
